From Expandable Graphite to Superfine Graphite Powders, we will be your best partner.
The market for Expandable Graphite as a halogen-free Flame Retardant is growing very fast. ADT pioneers this development with the understanding that this can only be done with products of high and absolutely constant quality. Today ADT offers a great variety of Expandable Graphites to meet the different requirements of the market.

ADT Expandable Graphite flame retardant additives can be formulated to provide a flame retarded system. ADT Expandable Graphite is a material based on natural graphite ore. The ore is treated with sulfuric acid in what is called an intercalation process. The material is washed and neutralized to prevent corrosion of metal parts when processed by the user. Excessive shear should be avoided. ADT Expandable Graphite additives may be used in polyurethanes, sealants, coatings, and polymers. ADT Expandable Graphite additives may also be used in conjunction with other flame retardant additives to provide improved flame retardant Properties to a material.

Quality Production

ADT is committed to producing Expandable Graphite of high and consistent quality. The emphasis on quality is approved by ISO-Certification in China and REACH in Europe. All products are neutralized and washed before drying.
For drying alone, ADT uses three different drying systems. Before packaging all Expandable Graphite are sieved to avoid any contamination.
